1、 Otu ọkara (mmiri, mmanụ, ikuku) quenching

Otu ọkara (mmiri, mmanụ, ikuku) quenching: Na-emenyụ ihe arụrụ arụ arụrụala ọkụ ka ọ menyụọ okpomọkụ n'ime ihe na-emenyụ ọkụ iji mee ka ha dị jụụ kpamkpam. Nke a bụ usoro nkwụsị nke kachasị mfe, nke a na-ejikarị maka carbon steel na alloy steel workpieces nwere ụdị dị mfe. A ga-ahọrọ ihe na-emenyụ ọkụ dị ka ọnụọgụ ọkụ na-enyefe ọkụ, ike siri ike, nha, ọdịdị, wdg nke akụkụ ahụ.

3、 Nzọụkwụ quenching nke martensite Nzọụkwụ quenching nke martensite: ígwè na-austenitized, na mgbe ahụ na-emikpu n'ime mmiri mmiri ọkara (nnu bath ma ọ bụ alkali bath) na a okpomọkụ dịtụ elu ma ọ bụ ala karịa elu martensite ebe nke ígwè, na-edebe maka oge kwesịrị ekwesị. . Mgbe akụkụ dị n'ime na n'èzí nke akụkụ ígwè ahụ ruru ogo okpomọkụ, a na-ewepụ ha maka ikuku jụrụ oyi, na austenite na-adịghị mma na-eji nwayọọ nwayọọ ghọọ martensite. A na-ejikarị ya eme ihe maka obere workpieces nwere ụdị dị mgbagwoju anya na nrụrụ siri ike chọrọ, a na-ejikarị usoro a emenyụ ihe nchara dị elu na nnukwu alloy steel. 4、 Ngwunye quenching nke martensite n'okpuru ebe Ms ka a na-eme ka quenching nke martensite n'okpuru ebe Ms: mgbe okpomọkụ bat dị ala karịa Ms nke nchara eji arụ ọrụ ma dị elu karịa Mf, workpiece na-ajụkwa ngwa ngwa na bat, na otu nsonaazụ ahụ ka nwere ike. a ga-enweta mgbe nha dị ukwuu. A na-ejikarị ya eme ihe maka nnukwu ihe eji arụ ọrụ igwe siri ike dị ala. 5、 Bainite isothermal quenching method Bainite isothermal quenching method: mebie workpiece n'ime bath na ala bainite okpomọkụ nke nchara na isothermal, nke mere na ọ nwere ike na-enwe obere bainite mgbanwe, na n'ozuzu na-edebe ya na bath maka 30 ~ 60min. The bainite isothermal quenching usoro nwere isi nzọụkwụ atọ: ① austenitizing; ② ọgwụgwọ jụrụ oyi mgbe austenitization; ③ Bainite isothermal ọgwụgwọ; A na-ejikarị na alloy steel, nnukwu carbon steel obere akụkụ, yana ihe nkedo ductile. 6、 Usoro nkwụsị nke ngwakọta

Ngwakọta quenching usoro: na workpiece bụ quenched n'okpuru Ms iji nweta martensite na olu nta nke 10% ~ 30%, na mgbe ahụ isothermal na ala bainite mpaghara nweta martensite na bainite owuwu maka workpieces na nnukwu cross ngalaba, nke a na-ejikarị maka. alloy ngwá ọrụ ígwè workpieces. 7、 Precooling Isothermal Quenching Method Precooling Isothermal Quenching Method: A makwaara dị ka Temperature Rise Isothermal Quenching, a na-ebu ụzọ mee ka akụkụ ahụ dị jụụ na obere okpomọkụ (karịa Ms) bath, wee bufee ya na bath okpomọkụ dị elu iji nweta mgbanwe nke isothermal nke austenite. Kwesịrị ekwesị maka akụkụ ígwè na-adịghị mma hardenability ma ọ bụ workpieces na ibu akụkụ na-achọ isothermal quenching.

8、 Usoro nkwụsị jụrụ oyi na-egbu oge

Usoro nkwụsị jụrụ oyi na-egbu oge: A na-ajụrịrị akụkụ ndị ahụ ka ọ dịtụ elu karịa Ar3 ma ọ bụ Ar1 n'ikuku, mmiri ọkụ, ma ọ bụ bath nnu, wee tinye ya na otu ọkara quenching. A na-ejikarị eme ihe maka akụkụ nwere ọdịdị dị mgbagwoju anya, ọkpụrụkpụ dị iche iche n'akụkụ dị iche iche, na-achọkwa nrụrụ ntakịrị.

9, Quenching onwe tempering usoro: Kpoo niile esichara workpieces, ma n'oge quenching, naanị akụkụ ndị dị mkpa ka obi sie (na-emekarị na-arụ ọrụ akụkụ) na-mikpu na quenching ngwọta maka jụrụ. Chere ruo mgbe akụkụ ndị a na-emikpughị na-apụ n'anya, ma wepụ ha ozugbo maka oyi na ikuku. Usoro nkwụsị na nke onwe ya na-eji okpomọkụ nke na-adịghị mma kpamkpam site na isi na-ebufe n'elu, na-eme ka elu ahụ dị ọkụ. Ngwa ndị a na-ejikarị egbochi mmetụta, dị ka chisel, ọkpọ, hama, wdg. 10、 Usoro ịgbanyụ ọkụ: Usoro nkwụsị nke a na-efesa mmiri n'elu workpiece, na mmiri na-erugharị nwere ike ịbụ nnukwu ma ọ bụ obere, dabere na omimi nke quenching achọrọ. The ịgba quenching usoro adịghị etolite a vepo film n'elu nke workpiece, nke ana achi achi na a miri hardening oyi akwa na-enwetara karịa quenching na Xitong mmiri. A na-ejikarị emenyụ elu mpaghara.
